Abstract
In the recent decade, single-shot ultrafast optical imaging by active detection, called single-shot active ultrafast optical imaging (SS-AUOI) here, has made great progress, e.g., with a temporal resolution of 50 fs and a frame rate beyond 10 trillion frames per second. Now, it has become indispensable for charactering the nonrepeatable and difficult-to-reproduce events and revealing the underlying physical, chemical, and biological mechanisms. On the basis of this delightful status, we would like to make a review of SS-AUOI. On the basis of a brief introduction of SS-AUOI, our review starts with discussing its characteristics and then focuses on the survey and prospect of SS-AUOI technology.
